Dillon was questioned behind closed doors for more than three hours today in Lansing.

Gov. Rick Snyder was deposed Wednesday and asked about retiree pensions and if Detroit could have done more to avoid the July 18 bankruptcy petition by state-appointed emergency manager Kevyn Orr.

Dillon said today in a statement that "the decision to seek bankruptcy protection was not an easy one but was determined to be the only remaining way to address Detroit's long-running financial crisis."

Their testimony can be used as evidence in an upcoming trial that will determine whether Detroit is eligible to shed or restructure at least $18 billion in debt in U.S. Bankruptcy Court.
